OK Motorcycles

OK motorcycles were manufactured from
1899 till 1939: from 1926, when one of the controlling
partners left the firm, the company was renamed OK
Supreme. The company had some success in racing in
the twenties and was sufficiently well established
to overcome the downturn in trade in the Depression
years. From the late twenties the company used SV
and OHV JAP engines only.

Following the dissolution of the founding
partnership in 1927, Ernest Humphries appended Supreme
to the original marque, and a year later OK-Supreme
had won their first and only TT win in the Isle of
Man with Frank Longman's victory. By the 1930s, all
OK-Supremes were four-strokes with JAP or Matchless
motors. After the Second World War, however, the logo
only ever appeared on a few grass track racing bikes.
